java書店系統畢業設計總體設計（1）

java書店系統項目功能需求：

1、能進行操作用戶的註冊，修改基本信息，刪除和查詢。
2、能對圖書的基本信息進行增加、刪除、修改和查詢操作。
3、能填寫進貨單，一張進貨單帶有多條具體的進貨信息，進貨的書籍必須是圖書管理裡面已經有的；進貨的同時修改庫存對應書籍的存貨量。
4、能填寫銷售單，一張銷售單帶有多條具體的銷售信息，銷售的書籍必須是圖書管理裡面已經有的，而且銷售的數量不能超過當前庫存的數量；銷售的同時修改庫存對應書籍的存貨量。
5、可以查看庫存的明細，可以按照條件進行查找具體的圖書的庫存值。
6、權限方面進行簡化，做固定的權限控制。把用戶按照模塊分成不同操作權限的人員，特設一個admin的用戶，可以操作全部的功能。

項目基本設計：

★ 架構設計：
整體框架、模塊劃分模塊劃分：用戶、圖書、進貨、銷售和庫存5個模塊

★ 系統功能結構設計：
每個功能模塊的具體功能子模塊★ 數據庫設計：
項目框架實現：分模塊、分層、分包、構建應用程序核心框架―-實現每個界面的轉換
